Simple electronics Code Lock System

SIMPLE ELECTRONIC CODE LOCK The circuit diagram of a simple electronic code lock is shown in figure. A 9-digit code number is used to operate the code lock. When power supply to the circuit is turned on, a positive pulse is applied to the RESET pin (pin 15) through capacitor C1. Thus, the first output terminal Q1 (pin 3) of the decade counter IC (CD 4017) will be high and all other outputs (Q2 to...

Ground Loops

What is ground loop ?A ground loop occurs when there is more than one ground connection path between two pieces of equipment. The duplicate ground paths form the equivalent of a loop antenna which very efficiently picks up interference currents. Lead resistance transforms these currents into voltage fluctuations. As a consequence of ground-loop induced voltages, the ground reference in the system...

Knowing electrical switch

In energy technological innovation, a change is a handled factor that can break a handled routine, uncomfortable the present or direction-finding it from one conductor to another.[1][2] The most familiar way of change is a independently handled electromechanical system with one or more locations of electrical powered handled managed handled connections, which are attached to exterior journey....

VHF field strength meter

This is a simple and low cost wide band VHF field strength meter. The field strength is measured by converting the radio signal to DC and measuring it.The RF signal will be picked up by the coil and rectified by the diode D1.Even a very small DC voltage is sufficient to alter the biasing of FET and it will be reflected in the meter as an indication of the presence of a radio signal. The meter can...

Whistle Responder

This device beeps intermittently for approx. two seconds when a person in a range of about 10 meters emits a whistle. The first two inverters contained in IC1 are used as audio amplifiers. IC1A amplifies consistently the signal picked-up by the small electret-microphone and IC1B acts as a band-pass filter, its frequency being centered at about 1.8KHz. The filter is required in order to select a specific...

Build A Relay Toggle Switch

Half of RL1 and RL2 manipulate the switching and the other is connected to an application. Relays are 200 ohms above ground and at one point are referenced to positive that turns them off.Description:RL1 (which is off) applies plus voltage from its armature and latches RL2 “on”. The application terminals are set to [A]. The condition changes when S1 is activated, voltage is applied to RL2 latching...

Simple Multiple Continuity Tester

The continuity tester is a handy adjunct to an ohmmeter. The unit or component whose continuity is to be checked is connected between terminals E1 and E2 (which may be probes or croc clips). The test current then flowing through the unit/component on test causes a potential drop across resistor R2, which is applied to the non-inverting input of buffer IC2. The output of the op amp is applied...

LED Camera

The process mentioned below shows how we can convert the LEDs to the light sensors so that it can be used for many other purposes also. Read on to know more about this.As the Blinkenlight Shield has 20 of them, 20 pixel camera can be developed by it. After performing the experiment, it is recommended to reset the jumper setting to default. LED or Light Emitting diodes usually act as the...
